An efficient and practical decarboxylative cross-coupling reaction of quinolin-4(1H)-one 3-carboxylic acids with (hetero)aryl halides has been established. Under a bimetallic system of PdBr(2) and silver carbonate, the protocol proved to be general, and a variety of 3-(hetero)aryl 4-quinolinones and related heterocycles, such as 3-aryl-1,8-naphthyridin-4(1H)-ones, 3-arylcoumarins, 3-arylquinolin-2(1H)-ones, and 2-arylchromones, can be prepared in good to excellent yields.
建立了一种高效实用的喹啉-4(1H)-酮 3-羧酸与（杂）芳基卤化物的脱羧交叉偶联反应。在 PdBr(2)和碳酸银的双金属体系下，该方案被证明是通用的，可以制备各种 3-（杂）芳基 4-喹啉酮和相关杂环，如 3-芳基-1,8-萘啶-4(1H)-酮、3-芳基香豆素、3-芳基喹啉-2(1H)-酮和 2-芳基色酮，产率良好至优秀。
